ABSTRACT
OBJECTIVE: Several adjustments occur after nephrectomy (NT) in the donor's remnant kidney. We investigated kidney donors 10 years after NT and compared several parameters before and after transplantation. METHODS: A total of 42 kidney donors of the University of Luebeck's Transplant Center were scheduled for a 10-year follow-up and were offered several investigations: laboratory tests, urinalysis and kidney ultrasound examination including determination of kidney volume (KV), resistive index (RI) and pulsatility index (PI). Moreover, a 24-hour ambulatory blood pressure monitoring (ABPM) was performed. A review of the medical records allowed comparison of the investigated parameters before (t0), 1 month after (t0.1), and 10 (t10) years after NT. RESULTS: Creatinine clearance decreased from 94.3 ± 23 (t0) to 52.4 ± 22 mL/min/1.73 m2 (t0.1) and increased to 78.2 ± 19 mL/min/1.73 m2 after 10 years (t10). Tubular proteinuria (α1-microglobuline) increased from 6.1 ± 1.5 (t0) to 63 ± 4.8 (t0.1) (P < .05) and decreased to 36 ± 2.4 mg/g creatinine at t10 (P < .05). Ultrasound examinations revealed a growth of the KV from 159.8 ± 23.1 (t0) to 175.5 ± 22.1 mL (t10) (P < .05) and an increase of RI and PI from t0 of 0.63 ± 0.01 and 1.03 ± 0.03 to t10 of 0.72 ± 0.04 (P < .05) and 1.24 ± 0.11 (P < .05), respectively. Post-NT ABPM values were not significantly different from pre-NT values. CONCLUSIONS: NT leads to hypertrophy of the remnant kidney associated with an increase of organ volume and creatinine clearance after 10 years of follow-up. Our results indicate an excellent prognosis for the kidney donors without any signs of renal damage.

BACKGROUND: Rare information exists about comparative long-term observations of patients with facial movement disorders. This retrospective analysis deals with the course of different parameters of injection over the time. METHODS: In this study we compared the development of long-term botulinum toxin treatments of patients with blepharospasm, hemifacial spasm and synkinesis. 80 patients (n=30 blepharospasm, n=31 hemifacial spasm, n=19 synkinesis), who had at least 10 consultations for BTA-injections, were included in the retrospective analysis. The development for each entity in total dosage, increase in the number of injection points and change in dosages for each point were evaluated. RESULTS: The over-all dosage in all 3 clinical disorders and for each single disease itself increased continuously over the time. The amount of injection points increased in the treatment of hemifacial spasm and synkinesis. The dosage per point increased most in blepharospasm between the 1. and 25. injection, but was distinctly lower in patients with hemifacial spasm and synkinesis. The increase in dosage in blepharospasm is therefore, in contrast to the other indications, mostly caused by an increase in dosage per point. In patients with hemifacial spasm and synkinesis the escalation of dosage is mainly caused by an increase of the number of injection points. CONCLUSION: These new aspects of the dynamic in the treatment with botulinum toxin enable the physician to understand better the dynamic of these diseases, to optimize treatment protocols.

After laryngectomy, the transport of intranasal secretions is often inadequate due to the lack of the nasal ventilation. Consequently, persistent and disruptive anterior rhinorrhea may occur. We report the case of a 61-year-old man who had recently undergone a laryngectomy and who was successfully treated with bilateral injections of botulinum toxin into the anterior portion of the inferior turbinates. After treatment, rhinorrhea was clearly reduced. Therefore, symptomatic treatment of anterior rhinorrhea with local injections of botulinum toxin type A should be considered as an option to improve the quality of life in laryngectomized patients.
ABSTRACT
Hypersalivation describes a relatively excessive salivary flow, which wets the patient himself and his surroundings. It may result because of insufficient oro-motor function, dysphagia, decreased central control and coordination. This reduces social interaction chances and burdens daily care. Multidisciplinary diagnostic and treatment evaluation is recommended already at early stage and focus on dysphagia, and saliva aspiration. Therefore, a multidisciplinary S2k guideline was developed. Diagnostic tools such as fiberoptic endoscopic evaluation of swallowing and videofluoroscopic swallowing studies generate important data on therapy selection and control. Especially traumatic and oncologic cases profit from swallowing therapy programmes in order to activate compensation mechanisms. In children with hypotonic oral muscles, oralstimulation plates can induce a relevant symptom release because of the improved lip closure. In acute hypersalivation, the pharmacologic treatment with glycopyrrolate and scopolamine in various applications is useful but its value in long-term usage critical. The injection of botulinum toxin into the salivary glands has shown safe and effective results with long lasting saliva reduction. Surgical treatment should be reserved for isolated cases. External radiation is judged as ultima ratio. Therapy effects and symptom severity has to be followed, especially in neurodegenerative cases. The resulting xerostomia should be critically evaluated by the responsible physician regarding oral and dental hygiene.

Spastic entropion is a rare condition that predominantly affects older people. We report on a 74-year-old dementia patient who was successfully treated by botulinum toxin injections into the lower eyelid, thereby avoiding lid correction surgery. For patients with an increased risk of eyelid surgery, symptomatic therapy comprising botulinum toxin injections to the lower eyelid should be considered as an alternative treatment.

Involuntary facial movements are caused by various diseases. This article describes three of these diseases: blepharospasm, hemifacial spasm and facial synkinesis following facial nerve paralysis. The different etiologies, clinical symptoms and diagnosis are discussed. A common therapeutic approach for these three diseases is presented. Involuntary facial movements can be reduced or even completely suppressed by local injections of botulinum toxin.

The production of sweat in the temporal skin region may be a serious problem for patients with hearing aids, active middle ear implants or cochlear implants. We report on two patients suffering from a loss of function of their hearing aid and a reduction of the "wear comfort" of an active middle ear implant. The patients underwent intracutaneous botulinum toxin (BTX) treatment of the temporal skin region. In both patients a distinct improvement of their complaints occurred, enabling them to use their hearing aids and active middle ear implants continuously. BTX injections are suited to improve sweat-caused complaints in patients with hearing aids, active middle ear implants and cochlear implants.

BACKGROUND: There are no regional data about the prevalence and use of botulinum toxin (BoNT) in otorhinolaryngology (ORL) departments in Germany. In order to obtain an overview of the current applications of BoNT in ORL departments a survey was carried out. MATERIALS AND METHODS: Standardized multi-choice questionnaires were mailed to 150 ORL departments. In the analysis a differentiation was made between university and regional departments. Also an analysis of the whole collective of respondent hospitals was carried out. The most commonly treated indication is the Frey syndrome followed by hypersalivation due to a salivary fistula after parotidectomy, dysphagia, aesthetic application and laryngeal dystonia. RESULTS: The rate of return was 62% and 75% of all responding hospitals use BoNT as a therapeutic option, especially where "off-label-use" indications are concerned (15 out of 20 indications or 75%). DISCUSSION: BoNT is widely used as a therapeutic option with an increasing trend. Due to different applications a schedule of hospitals would be helpful in order to be able to find the nearest hospital for the appropriate indications.
